Abstract:
A sensor comprises a preferably multilayered ceramic substrate (2) and at least one sensor element (1) arranged in, at or on the ceramic substrate (2). Contact can be made with the sensor element (1) via a metallic contact (6), wherein the metallic contact (6) is produced by means of a soldering connection that electrically connects the contact (6) to the sensor element (1) and in the process produces a fixed mechanical connection of the contact (6) relative to the ceramic substrate (2). A method for producing the sensor according to the invention is furthermore claimed.
Abstract:
Systems and method for using a direct connect RF pin configuration for an ONU transceiver module to connect directly to an external component. The ONU module communicates with an optical network. The ONU module further includes an RF interface and a direct connect RF pin configuration to communicate using RF signals. In one embodiment, the direct connect RF pin configuration includes two ground pins and a data pin which are spaced apart and directly connected to a PCB of the ONU. The opposing ends of the pins are directly connected to a PCB of an external component, such as an ONU host box. The pins are thus spaced apart such that they do not impede each others' function and available for direct connection to the external component.

The present invention is directed to a plug-in device (12) having a printed circuit board (14). A plurality of conductor pins (26) arranged in a circular configuration are surface mounted or through-hole mounted to the circuit board (14) and extend outwardly therefrom. A plastic base (24) with a key shaft (102) is secured to the circuit board (14) over the conductor pins (26). The key shaft and the conductor pins are adapted for insertion into a socket. The circuit board may be insert-molded into the plastic base, or the plastic base may be pre-formed and secured to the circuit board by heat staking and/or adhesive.
Abstract:
When the ceramic substrate of a ceramic column grid array is connected with a large number of columns, a mounting jig is arranged on the ceramic substrate and a column is inserted into the hole of the mounting jig. When the columns are inserted one by one into the holes of the mounting jig, the productivity is low and the cost increases. A column suction head enables the columns to be inserted into all holes of the mounting jig at a time. Elongated holes are bored in the body at the same positions as those of the electrodes provided on the ceramic substrate of the ceramic column grid array and a suction hole is bored in the bottom of each elongated hole. When a column suction head is set on an arranging jig where the columns are arranged and air is sucked through the suction holes, the columns of the arranging jig are sucked into the elongated holes of the column suction head.
Abstract:
Die Verbindungsanordnung umfasst mindestens zwei Schaltungsträger (1, 2), wobei jeder Schaltungsträger jeweils eine Seite mit elektrischen Kontaktierungsflächen (10, 15) aufweist. Mindestens eine Kontaktfläche (10, 15) des einen Schaltungsträgers (1) ist mit mindestens einer Kontaktfläche (15) des anderen Schaltungsträgers (2) über ein Verbindungselement (20) elektrisch leitend verbunden. Um kostengünstig auch eine feste mechanische Verbindung der beiden Schaltungsträger ohne zusätzliche Halterungen zu realisieren, verbindet das Verbindungselement (20) die beiden Schaltungsträger zugleich mechanisch fest miteinander, wobei die verbundenen Kontaktierungsflächen der beiden Schaltungsträger so positioniert sind, dass die Schaltungsträger in einer vorgegebenen Relativlage zueinander fixiert sind.
